Nonlinear Dimensionality Reduction by Locally Linear Embedding

Many areas of science depend on exploratory data analysis and visualization. The need to analyze large amounts of multivariate data raises the fundamental problem of dimensional...

Mining association rules between sets of items in large databases

We are given a large database of customer transactions. Each transaction consists of items purchased by a customer in a visit. We present an efficient algorithm that generates a...

Raman Spectrum of Graphene and Graphene Layers

Graphene is the two-dimensional building block for carbon allotropes of every other dimensionality. We show that its electronic structure is captured in its Raman spectrum that ...

Principal Component Analysis

Abstract When large multivariate datasets are analyzed, it is often desirable to reduce their dimensionality. Principal component analysis is one technique for doing this. It re...

A Multi-Modal Distributed Real-Time IoT System for Urban Traffic Control (Invited Paper)

Traffic congestion is one of the growing urban problem with associated problems like fuel wastage, loss of lives, and slow productivity. The existing traffic system uses program...

MOLSCRIPT: a program to produce both detailed and schematic plots of protein structures

The MOLSCRIPT program produces plots of protein structures using several different kinds of representations.Schematic drawings, simple wire models, ball-and-stick models, CPK mo...

Harmonizing the Metabolic Syndrome

A cluster of risk factors for cardiovascular disease and type 2 diabetes mellitus, which occur together more often than by chance alone, have become known as the metabolic syndr...

Dynamic capabilities: what are they?

This paper focuses on dynamic capabilities and, more generally, the resource-based view of the firm. We argue that dynamic capabilities are a set of specific and identifiable pr...

Energy-efficient communication protocol for wireless microsensor networks

Wireless distributed microsensor systems will enable the reliable monitoring of a variety of environments for both civil and military applications. In this paper, we look at com...

PhysioBank, PhysioToolkit, and PhysioNet

Abstract —The newly inaugurated Research Resource for Complex Physiologic Signals, which was created under the auspices of the National Center for Research Resources of the Nati...

Exchange and Power in Social Life.

In his landmark study of exchange and power in social life, Peter M. Blau contributes to an understanding of social structure by analyzing the social processes that govern the r...
